Pipeline fails with “clone: skipped” (Docker stack)

As HC89 solved the problem,

Could you please follow his steps?

  1. specify the version for the server and client Docker images to :1 ,
    (ONLY if you face an error without this)2. added the environment variable DOCKER_API_VERSION: 1.39
  2. changed the network to an attachable and external one in order to allow the Drone runner to attach its own containers to it.
